Former mobile giant BlackBerry is suing Nokia for patent infringement, six months after it stopped production of its hardware.

In a 96-page lawsuit, reported in ArsTechnica, the company claims Nokia infringed 11 BlackBerry technology patents "related to LTE- and UMTS/UTRAN-compliant products and services".

These include "a number of transmit antennas found in a base station" and a "scattered pilot pattern and channel estimation for MIMO-OFDM systems", adds the website.

Some of the patents were previously owned by Nortel Networks, which Nokia attempted to purchase in 2009, reports Bloomberg.

According to TechCrunch, the lawsuit doesn't request Nokia terminate its use of BlackBerry's patents, but instead looks to "collect on damages related to the royalty fees it charges for licenses on the technologies".

BlackBerry announced last September it was ending production of its devices to instead focus on developing software for other smartphone manufacturers.
